The electrification of the transportation sector is an important step to ensure a sustainable system. It offers a promising solution to reduce oil consumption, decrease Greenhouse Gas (GHG) emissions, improve air quality, increase transportation sector efficiency, and it can play an important role in the integration of renewable energy resources into the electric grid. However, one of the biggest bottlenecks of the electrification of vehicles is the requirement for various charging infrastructure options. Three technologies have emerged as game-changers: Dynamic Wireless Charging (DWC), Battery Swapping Stations, and Fast Charging Stations (FCSs). These advancements have the potential to increase the adoption of Electric Vehicles (EVs) by addressing critical challenges such as range anxiety and charging downtime issues of EV users. The primary focus of this work is on FCS, which currently represents the most readily available option in the market. To ensure the optimal utilization of this charging infrastructure, it is important to address the challenges related to routing EVs to the nearest FCS that can meet the EV charging requirements, such as wait time, charging duration and charging cost. Vehicle-to-Everything (V2X) and the Internet of Vehicles (IoV) will play a critical role in enhancing EV routing to the FCS. Additionally, the coordination of EV charging demand is essential to achieve grid load balancing and prevent grid overload. The main focus of this paper is to present the vision and future trends of Smart Green IoV in the era of electric vehicles for sustainable V2X connectivity, grid integration, vehicular networking, data security, and services.INDEX TERMS Internet of vehicles, plug-in charging, wireless charging, electric vehicles, battery swapping stations, V2X technology, machine learning, power grids, sustainability.

“…In practice, the leakage inductance L s -M and C f2 can be regarded as one device, which may be an inductor L se or a capacitor C pe . According to (5), when the sum of the impedances of the three resonant elements in the Π−style resonant network is equal to zero, a CC output independent of the load change can be obtained. The resonant condition of M, C p2 , L se , and C pe can be given as follows:…”

The inductive power transfer (IPT) method is an emerging charging technology that has some advantages over traditional plug-in systems. For example, it is safer, more convenient, and efficient, leading to its widespread acceptance. To design an IPT charger capable of providing a load-independent output, this paper proposes a secondary side-controlled hybrid-compensated topology used in the IPT system to charge the battery with a constant current/voltage output. According to an analysis of the Π-type network, effectively using the existing configuration compensation parameters and adding two AC switches to perform hybrid-topology switching reduces the system’s passive components. Additionally, the proposed IPT charger can easily realize zero-voltage switching. The secondary side-based control omits wireless communication links. Moreover, the control strategy is relatively simple, enhancing the system’s reliability. We designed a 1.4 kW experimental prototype with a 15 cm air gap between the transmitter and receiver to verify the proposed hybrid-compensated IPT system’s feasibility.

“…T HE interest for wireless power transfer (WPT) using magnetic coupling in different common applications has been booming since the Massachusetts Institute of Technology (MIT) developed a highly efficient WPT resonant system in 2007 [1]. These applications include wireless power transmission systems for wireless charging of cellular phones [2][3][4][5], electric vehicles [6][7][8][9][10][11][12], and medical equipment [13][14][15][16][17][18][19][20]. For wireless power transmission resonant systems, the ability to measure or predict the magnetic coupling between the coils of the system is fundamental, and having expressions to compute the magnetic field generated by the coils is very useful.…”
